1. SURFACE-MOUNT SUMP PUMP – Untreated wash water is introduced into the system via a 1.0 HP surface-mount
sump pump, which is included with the system.
2. CORONA DISCHARGE OZONE SYSTEM – As the wash water is pumped into the water/oil/solids separator and it is
injected with a high concentration of ozone via a corona discharge ozone injector system for a "quick kill" of live bacteria on
contact. Ozone also breaks up emulsified oils, allowing them to coalesce and float to the top of the tank for separation into the
oil decanter.
3. THREE STAGE STAINLESS-STEEL TANK – As the water flows through the stainless-steel three stage water/oil/solids
separator, it changes the overall flow direction several times as it flows around four vertical baffles. The water is slowed down
and fine silt and solids drop to the bottom of the tank.
4. BIO-FILM GENERATIVE MEDIA – As the water progresses through hundreds of square-feet of honey-combed-shaped
meshed oleophilic (oil-attracting) coalescing media, it will change directions countless times. In this process, mechanically
emulsified oil particles are attracted from the water to the oleophilic media and float to the surface.
5. OIL SKIMMER/DECANTER – Once the oil floats to the water's surface, it is then skimmed into an oil decanter for
easy disposal.
6. SLOPED SOLIDS TRAP – Fine silt and particles are dropped to the bottom of the sloped stainless-steel tank for easy
flushing and disposal.
7. DISCHARGE PORT – Once the water has been treated, it flows into the final chamber of the stainless-steel tank and then
through a 2-inch drain line to a sanitary sewer drain in the floor.
8. ELECTRICAL CONTROL PANEL – ETL listed NEMA-4 rated corrosion-proof control panel for safe and reliable operation.

THE IMPORTANCE OF
A PROPER PIT SYSTEM:
Once equipment is washed, the untreated
wash water flows into your pit system.
A proper pit system for your application
is the first step in proper wash water
treatment and a critical element in any
wash water recycle system.
Consult your dealer to determine the pit
system configuration that works best
for your application.

Process & Flow Description

1. CLARIFIER TANK – 600-gallon cone-shaped clarifier settles solids. Free-floating oils are removed via a
suspended oil skimmer. Model WCL-30D-0M10 has 425 sq. ft. of oil coalescing media to help capture mechanically emulsified oil.
2. ELECTRICAL CONTROL PANEL – ETL listed NEMA-4 rated corrosion-proof control panel for safe and reliable operation.
(Standard on WCL-30D-0M10)
3. CORONA DISCHARGE OZONE INJECTION – For odor control and breaking emulsified oils, the WCL-30D-0M10 comes
with a corona discharge ozone generator. The ozone generator has an output of 0.5 grams per hour of ozone for a "quick kill" of live
bacteria on contact. Ozone also breaks up emulsified oils, allowing them to coalesce and float to the top of the tank for separation
into the oil decanter.
4. TREATED WATER HOLDING TANK (Accessories #855-0015, 80-gallon capacity and #855-0016, 165-gallon capacity) –
Treated water holding tank for transferring water to the next
process or point of discharge.
5. SOLIDS SEPARATION CHAMBER – Solids from
the wastewater stream settle at the base of the clarifier
tank. With the opening of a single valve, solids are
easily dropped into a bag filter in the solids
separation chamber for effective capture and easy
disposal. The bag filter is suspended on a
dewatering tray with drainage returning to the
in-ground collection pits.
6. SURFACE-MOUNT SUMP PUMP –
Untreated wash water is introduced into the
system via a 1.0 HP surface-mount sump pump,
which is included with the system.
7. OIL DECANTER – Oil skimmed from the surface
of the clarifier tank is captured in a conveniently
located oil decanter. Oil can be easily removed for
appropriate disposal.
